as shown in the drawing, and permit a free flow of air between thetubes, and thus insure complete and proper combustion of the gas.

The housing 5 supports upon the interiorl thereof a melting cup 20. Theupper portion of this cup is preferably substantially circular, whilethe lower portion as indicated at 2l is conical in shape. At the bottomthe conical portion 21 is truncated and formsan opening 22. y

Upon the lower portion 21 of the melting cup there is pivotally secureda chute or guide 23. This chute is in position to receive material whichmay pass through the opening 22 and guide it into the melting pot 41. Aswill be seen from the drawing, the tube 10 is in position to direct aflame due to the burning of the gas at theend or' 'the tube 10 in adirection down and along chute 23, thus keeping the chute 23 in heated.condition so that any molten metal passing from ethe cup 21 will notfreeze in the chute 23.

Upon the housing 5 there, is supported a substantially cylindricalprotecting casing 24. rlhis casing is formed at its lower end with aring 25, to which ring are secured brackets 26. The brackets extendinwardly and engage a ring member 27, which is of slightly less diameterthan the interior of the cup 20. Extending upwardly from the 4 ring 27are guiding members 28. These members at their upper end arc secured toa ring 29, and intermediate their ends are secured to a circular member30, which circular member engages with the upper'end of the protectingcasing 24. The casing 24ris secured upon the platform 4 in any desiredImanner and is preferably removably secured. f

The guiding members 28 are adapted to receive a-cylindrical ingot oftype metal, the diameter' of which is such that it will easily passthrough the ring 27, so that the lower portion ot' the ingot lwill restwithin the melting pot 20. Q

When heat is applied to the melting pot through the burner 6, the typemetal of ingot will be melted and run down the conical wall 21 of themelting cup lunder the chute 23, and thence drop into the melting pot 1.Gradually the ingot of metal will at its lower portion coliform to thewall 21 of the meltingcup, and therefore will be subjected substantiallydirectly to the heating etlectof the burner 6.

Obviously, additional ingots of type metal may be placed one on top of'the other within the guide members 28, so that when the device has oncestarted to operate, there will always be present within the melting cup20 an ingot or portion of an ingot which will conform to the conicalportion 21 of the melting cup.

Leashes The melting cup 20 may be supported within the housing 5 in anydesired manner, and for the purpose, T have shown legs, one of which isindicated at 30. These legs will serve to position the melting cup sethat the lowest conical portion thereof will extend centrally throughlthe burner 6.

The inner face or wall 16 of the burner as well as the inclination ofthe tubes 1S, is such that they extend substantially parallel with theconical portion 21 of the melting cup; therefore, the flame produced bythe burning of ,the gas at the burner G and the tubes 18, is directedsubstantially upon the entire conical surface 21 of the melting cup.

The burner 6 with its tubes 1S forms a particularly desirable type ot'burner for use in the connection shown and described. lt is necessary toheat the entire conical surface 21 of the melting pot, but if a burneroi' the usual ringtype be used of suliicient height to cover the conicalportion 21 ot the top, it will be practically impossible for enough airto reach the burninggas to effect a complete combustion of the gas;consequently, considerable quantities of gas escape unconsumed, which isdangerous. lint what is of more importance is that it is ini- -face ornthe melting cup, and providing the upwardly extending tubes 1S, the gaswill be entirely burned, for if all the gas is not burned on leaving theopenings 17 ot'lhe, burner G, this gas will be subsequently burned, foras will be clear, air may lnd ready passage between the tubes 1S, sothat when the gas unburned at the burner (3 reaches the vicinity of thetubes 1S7 it will be ignited and consumed.

As heretofore stated, the ring 27 is o1 slightly less diameter than thediameter of the cup 20, and keeps the ingot from conn'iaintain the ingotcentral with respect io the cup 20, and keeps the ingot from contactingwith the upper edge oi the cup 20, so that there is no danger' of theingot melting at this point and running down upon the outside of thecup. Y

The particular shape which is given to the melting cup, that is to say,providing the. lower portion as a conical surface, prevents thecollection of any dross within the cup. The melted metal and any drosspresent will pass through the conical bottom portion 21. each succeedingingot as it descends into the. cup and iorms itself -to lit the tion ofthe melting cup, scrapes the wall of the cup and forces any dross anddirt which may perchance have adhered to the, wall, down and out of theopening 22. Consequently, whatever dross there may be will conical pow ie lill.

lllie member 3l is provided with n rounding surface, 'and when theplatform 4l is swung, to move the feeder away from the melting pot, themember 3l engages the edge of pot and due to the rounding ot member 3l,the chute elevated and so passes over the edge of the pot.
